This i invention relates to Ventilating devices for closet bowls and theprimary object is to provide a simple, efficient, and practicalmechanism for carrying ofi' offensive odors before they are permitted toescape into the ing and Ventilating, and thus render it un-.

necessary to provide`the bowl proper with other or additional equipmentfor connecting the Ventilating equipment. A further ob'ect is to rovidea ventilator tube with an e ectrical y operated fan or blower forcreating the necessary Ventilating current therethrough, and to insulatethe tube or flue from vibrations of the fan motor so as to eiectva 2oquiet operation thereof. A further object is to provide a circuitconnection for the fan motor including a switch that is automatically oened and closed by pressure on and oli ofv t e bowl seat whereby the fanwill be operative to eiect a forced ventilation only when the cover isopened and the seat is in use, but which will be inoperative when thecover is down as when the bowl is not in use. A further obJe'ct is toprovide an improved 3o and simple design of construction for the motor,fan, and fan housing, whereby the motor and fan may be readily removedfor cleanin oiling, or repair purposes. These and stil other objectswill be disclosed in the course of the following spx'aciiication,y ref-`erenee being had to the accompanying drawinz'm which s Y 1g. 1 is aside elevation of'a bowl, flush tank, and adjacent building parts, andshow- 40 in my improved Ventilating system as applied thereto. v

Fig. 2 is a sectional detail elevation throu h a modified form of thedevice, showing t e app1 ication of a motor and fan to the ventilatorflue.

Figi?, is a detail elevation, partly in section, showing a switchconnection to the bowl cover for automatically starting and stopping thefan motor. l

Fig. 4 is a .diagram atie plan view of the 50 circult system employedwith the fan motor.

Referring to the drawing more particularly and-.by reference characters,A designates any common and well known type of toilet bowl having a seatB and cover C, hingedly "secured as at D, said bowl being connected'to awater receptacle E by a flush pipe F, in the customary manner. I

To my knowled e ventilatlng and deodorant devices hereto ore applied tocloset bowls oo.

have required the use of separate parts projecting into the bowl, orformed therein, which is objectionable chiefly because of the cost orbecause of the diiliculty of so securing` such parts that they will notbe obstructive or in the way. To overcome these difficulties and at thesame time to provide a simple and practical arrangement for ventilatorcommunication with the bowl, I connect the lower endof the ventilatorilue 5 directly to the 70 flush pipe F, as at 6. Thus lthe lue 5 can inno way interfere with the function of the pipe F, and that pipe can inturn serve the double function above noted. The flue 5 has a damper 7,and extends with its upper end up through the ceiling of the building,where it may be provided, in its simplest form, with y a wind rotatedmetal hood or cowl8 to accelerate the updraft through the flue 5.

As'shown in Fig. 2 the flue 5 is provided with an enlarged, pear shapedhousing 9, havin a cover 10 secured as by wing nuts 11. A small electricmotor 12 is secured to the cover 10, and in turn carries a pair ofpropellers 13, which, when rotated, operate to create an updraft throughthe'lue 5. It will be noted that the housing 9 is secured tothe endsofthe upper and lower flue sections 5 by hose connections 14 which aresufficiently flexible so that vibrations and noise of the through theswitch 16, as by supply Wires 18.

In the modification shown in Fig. 3, the seat and cover ivot D anchorson a pair of vertically slida le posts 19 that are held in yieldablyraised positions, as by springs 20,

- but when depressed will act as a switch memsion of the ving a seatring 'and a v ber to close a circuit through the motor. The

cover C may be provided with a bracket rest 21, so that it will beimpossible to close the switch 19 when' the cover C is closed, which 1sa desirable feature especially when it may come necessary to use thecover C as an ordinary seat or support for other purposes. Itis undelstood that suitable modifications may be made in the structure asdisclosed,

provided such modifications come within thc spirit and scope of theappended claims.

aving now4 therefore fully illustrated and described my invention what Iclaim to be new and desire to protect by Letters Patent 1s:

1. The combination with a closet bowl having a seat ring and a covertherefor, of a depressible bearing member hingedly supporting the ringand cover, a ventilator for the bowl, means rendered operative bydepression of the caring member when pressure is applied to the seatring to actuate the ventilator, and means carried by the cover to lockthe bearing member in its normally raised or inactive position when thecover is closed.

2. The combination Witha closet bowl having a seat ring and a covertherefor, of a depressible bearing member hingedly supporting the ringand cover, a ventilator for the means rendered operative bydepresbearing member when pressure is applied to the seat ring toactuate the ventilator, and means rendered operative by closing thecover to lock the bearing member in its raised or inactve position.

8. The combination with a closet bowl havcover therefor, of a motoractuated ventilator for the bowl, a circuit for the motor, a.depressible member forming a hinge bearing for both the seat ring andthe cover, a switch in the circuit arranged to be closed by depressingthe bearing` member, and means rendered Adperat-ive by closing the coverto switch in its circuit opening position.

` 4. The combination with a closet bowl having a seat ring and a coverhinged with rerenderl the ventilator actuating means inactive.
